I bought two: one of which arrived with an irreparable hole in the material, and the other which within a week both lost its shape (it turned into a ball, rather than a seat), and then developed three separate holes in the plastic seams. Considering the chairs were used properly, only about 3 or 4 times, indoors, by adults, and both ended up unusable, the build quality of these chairs really has to be questioned. With that being said, whilst they were inflated and working, the chairs were comfortable enough and fit their use well.
I bought this in February, didn't need it till a music festival where camping until August. Therefore I hadn't used it. I got all pitched up at camping, blew my air mattress up and this inflatable chair. The 1st day it seemed to hold mostly but was deflating slowly so I added a bit more air when it lost 25% of air. The second day a seam seemed to split and there is no puncture repair kit with this chair. The chair was useless for the next two days of the festival and I had to sit on the floor.
Have contacted the seller, they ignored my first email and just closed my second email stating it is past the returns period. Considering I didn't use the product for 6 months as I got all my festival items early I find this shoddy and unacceptable from the seller. The chair in question was comfy but isn't of great quality and I fear the seams are easily split, as per what happened to mine.
